Therefore, according to present embodiment, follow the decompression in bottle 100, not only make outside movable wall part 122 centered by curved face part 125, together towards top, move with curve 123 and inaccessible wall section 124, and can make the inboard part of curve 123 move towards top.That is, can lift bottom wall part 119 to the inboard of bottle 1 by multistage steppedly.Thus, owing to can making bottom wall part 119 actively be out of shape, therefore can improve the decompression absorptive character of bottle 100.
In addition, when the interior decompression of bottle 100, when annular recessed portion 130 can be easy to enlarge radial dimension, be out of shape, and can be easily guaranteed the sufficient amount of movement towards top of curve 123.
In addition, in movable wall part 127 and depression surrounding wall portion 123b, with described annular recessed portion 130, compare the inboard part that is positioned at radially inner side, along the circumferential direction be formed with rib 137.This rib 137 connecting part 123c towards above with curved surface shape depression and form.Result is, as shown in the embodiment, in the situation that by the Biaxially stretched blow-molded bottle 100 that forms, the thickness of the centre portion between rib 137 and annular recessed portion 130 in curve 123 can be formed thinlyyer, and can easily make this centre portion distortion.Thus, can easily make the above-mentioned inboard part of curve 123 further be moved upward centered by annular recessed portion 130, thereby can conscientiously improve the decompression absorptive character.
Above, with reference to accompanying drawing, the second embodiment of the present invention is had been described in detail, but concrete structure is not limited to this embodiment, also comprise design modification that does not break away from aim scope of the present invention etc.
For example, in the above-described embodiment, the situation that the complete cycle at circumferencial direction is formed continuously to annular recessed portion 130 and rib 137 is illustrated, but is not limited to this, can also form intermittently at the complete cycle of circumferencial direction.
In addition, devices spaced apart forms a plurality of annular recessed portion 130 and rib 137 diametrically.
In addition, the section shape of annular recessed portion 130 and rib 137 is circle, rectangle etc., can also carry out suitable design modification.Further, can also change the size of annular recessed portion 130 and rib 137.
In addition, in the above-described embodiment, for when bottle 100 reduces pressure, the situation of carrying out in order rotation centered by curved face part 125 and the rotation centered by annular recessed portion 130 is illustrated, but be not limited to this, the order of the rotation centered by curved face part 125 and the rotation centered by annular recessed portion 130 can also be put upside down and carry out, or two kinds of rotation action are carried out simultaneously.
In addition, erect surrounding wall portion 121 and can also carry out suitable change, for example extend abreast with bottle axle O direction, or with the mode extension of tilting with respect to bottle axle O etc.
In addition, movable wall part 127 can also be carried out suitable change, such as with radial parallel give prominence to etc.
Further, can also not form jog 117a.
In addition, the synthetic resin material that forms bottle 1,100 can also carry out suitable change, such as being polyethylene terephthalate, PEN, non-crystalline polyester etc. or its composite material etc.
Further, bottle 1,100 is not limited to single layer structure, can also be the laminar structure with interlayer.As this interlayer, can enumerate such as the resin material by thering is gas barrier property, form the layer, by regrown material, formed the layer or by the resin material with oxygen uptake, formed the layer etc.
In addition, in the above-described embodiment, shoulder 12,112, body section 13,113 and bottom 14,114 are formed to toroidal with the cross section shape of bottle axle O quadrature respectively, but be not limited to this, can also suitably change to such as polygon etc.
In addition, within not breaking away from aim scope of the present invention, can suitably the structure member in the respective embodiments described above be transformed to known structure member, in addition, can also the above-mentioned variation of appropriate combination.
